The TomTom Go 730 and Go 930 are refreshes of their 720 and 920, with two new headlining features: IQ route and advanced lane guidance. Using data collected over the last year from other TomTom devices, IQ route actually tells you the best way to go depending on the day—like, the freeway on Saturday afternoon, but backroads on a Monday morning. Right now it's only by day, but as they collect more data, it'll be increasingly specific—morning vs. night, etc. Advanced lane guidance is basically a little movie demo of massive highway junctions and turnoffs, so you don't take the wrong one. Full specs below.

The innovative IQ Routes™ technology is based on actual average speeds measured on roads, rather than posted speed limits. This means that the new TomTom GO range determines a route by considering all possible routes and then selecting the one that takes the least time based on recent historical data. In almost 50% of all journeys, this results in a faster route, and saves significant travel time, fuel, and money.

In addition, the new TomTom GO series includes TomTom's Advanced Lane Guidance feature. Advanced Lane Guidance provides users with realistic representations of complex highway junctions and lane-specific visual directions that take the stress out of navigating these otherwise difficult junctions.

The two new features will be available with the new TomTom GO series, the TomTom GO 930 and TomTom GO 730, starting at the end of April 2008.

"With the introduction of IQ Routes™ technology, we continue to focus our efforts on features and content that improves the core navigation experience," said Jocelyn Vigreux, president of TomTom Inc. "IQ Routes™ delivers what we call 'intelligent routing' - an even smarter and more efficient way of planning your daily route that will help TomTom GO users save time, fuel and money."

TomTom IQ Routes™

The new TomTom IQ Routes™ technology is based on actual average speeds on roads, rather than the posted speed limits. This intelligent routing technology is based on anonymous historical speed profiles of over 6.2 billion miles of driven roads, gathered over the years by millions of TomTom users. It takes into account all the factors that may influence the time it takes drivers to get to their destination, including traffic lights, rotaries, steep slopes and speed bumps.

The TomTom IQ Routes™ speed profile database continues to grow at the rate of over half a billion measurements per day, so the time and spatial accuracy of TomTom IQ Routes™ technology will continually increase. Drivers can be confident that they will always be given the smartest route, incorporating detailed local knowledge. This allows for more efficient daily route planning, in particular when driving through urban and mountainous areas.

Advanced Lane Guidance

With the new Advanced Lane Guidance feature, navigating difficult junctions becomes easier than ever before. Advanced Lane Guidance provides users with realistic visuals of complex highway junctions and lane-specific directions. Static images of road signs, in the same color as the ones displayed on the road, ensure that drivers have an even more realistic view of the road ahead, and their specific route.

A host of extra features

In addition to IQ Routes™ and Advanced Lane Guidance, the new TomTom GO range has a new premium look with a high-quality finish, expanded map coverage and comes pre-installed with the latest navigation features, including:

- TomTom Map Share™ technology, enabling users to make updates and corrections to their own maps instantly and to benefit from improvements made by other users, completely free of charge. New Map Share features include the ability to change turn restrictions and posted road speeds

- Latest map guarantee so users always have free access to the latest map at time of purchase

- Voice address input so that users can drive to millions of cities and street names by simply announcing the address of their destination

- Clear voice instructions and text-to-speech to enable street names, places, traffic alerts and SMS messages to be read aloud as part of the spoken instructions
